FOSDEM 2014: Cisco Powered World First

For a few of us in the Cisco Brussels office the last weekend of January always marks a special occasion.

The weekend is dedicated to the Free and Open-source Software Developers’ European Meeting (FOSDEM) conference in Brussels, with around 5,000 visitors attending. The event happens at the ULB (Université libre de Bruxelles) campus, but traditionally uses its own network infrastructure, sponsored by Cisco. And we, who are Cisco employees, volunteered our time to help the community as well as meet some new friends and get extra hands-on experience with a sizable network.

What was different this year was that just before the official start of the conference I finally figured out how NAT64 works, gave a 5 minute warning on twitter (image below), and then disabled IPv4 on the main network (simply stated I removed the IPv4 address of the router on the client interface so that only the IPv6 address remained).

That meant that visitors would only get an IPv6 address Read More »

My Cisco Live Milan IPv6 Firsts

That is it, Cisco Live Milan is over! The “before” of anticipation, seemingly a moment ago, is replaced by the “after” of takeaways and accomplishments for the week. Some passed their CCIE certification, some met a new business partner, but it’s likely that everyone learned something new. I am not an exception.

During the week, I presented at two different technical breakout sessions (BRKRST-2304 -- Hitchhiker’s Guide to Troubleshooting IPv6 and BRKEWN-2666 -- IPv6 on WiFi: You talk too much! NOT anymore) and spent my remaining time working with everyone in the Network Operations Center (NOC) to ensure that IPv6 is a smooth ride for all of the 9,000+ devices on the network. Not only did I learn a lot, but this year at Cisco Live Milan was a year of “firsts” for me.

  • For starters, it was the first time I shared details about my experience with large-scale IPv6 WiFi setups with Cisco Live attendees in the form of a breakout session. After talking with attendees, my main takeaway -- Read More »

Get Inspired by Cisco Live Europe 2014

Cisco Live Europe 2014 (Milan) just ended and I think I will need a few days to reorganize my ideas. It was my first opportunity to attend #CLEUR, and moreover I did it as a CCIE.

CLEUR is not just a Cisco event (or should I say THE Cisco event) but also a unique opportunity to experience technology, expertise, vision, and inspiration.  And of course meet friends. Read More »

Touching / Seeing / Feeling IPv6 in the World of Solutions at Cisco Live Milan

As Cisco Live Europe 2014 draws to a close I wanted to reflect on what has (for me) been a personal campaign to raise the visibility of IPv6 in the World of Solutions / WoS (the demonstration / show floor of the event)

Last year at Cisco Live London I heard some comments that there was not enough IPv6 in the WoS. I decided to see if I could encourage Cisco Business Units and Partners to enable demonstrations for Dual Stack operation and highlight that fact. I wrote previously we would be “awarding” an “IPv6 Enabled Logo” to all Cisco and Partner demonstrations that took the step of enabling Dual Stack and highlighting the same fact.

How did we fare ? Cisco Live 2014 Milano showcased over 15 IPv6 enabled demonstrations including two which were enabled as “IPv6 only”. These were spread between Cisco and Partner booths and were mainly marked with the newly created green “IPv6 Enabled Logo”.

Quitting the Legacy IP at Cisco Live Milan

It’s that time of the year again -- time for some computer and human networking at Cisco Live Milan! This year I’m taking the unusual and somewhat risky step of blogging about the network infrastructure before the event. This is because we’re going to try something interesting for the networking folks. We are going to try and get rid of the Legacy IP, otherwise known as IPv4.

Before you get too worried -- no, the dual stack network setup does not disappear. Lots of critical parts of our everyday lives still need the old and proven protocol to successfully operate, so removing it would be irresponsible to say the least. But some of you may be interested to try (in a controlled fashion) exactly how strong the ties to the old good legacy. If you are one of these people, this post is for you -- because this blog entry is one of the few places, if not the only one, to find the IPv6-only SSID name and access credentials.

First of all, what’s the big deal with IPv6-only access network, wasn’t this tried before?

Sure, it is not all new. The first time we tried an IPv6-only network was at IPv6 World Congress conference in Paris, early spring 2012. We also had an IPv6-only SSID in one of the Cisco Live US conferences. We discovered that the subset of the operating systems that could successfully operate in this kind of environment was pretty small. But as time passed, evidence suggests the situation was slowly improving. Read More »
